ANTISMUTTING- DEVICE FOR TRAVELING SHEETS.

"Specification of Letters Patent.

Patented June 1, 1920.

Application filed November 6, 1915 Serial No. 60,074.

To all whomz't may concem:

Be it known that I, BERNARD D. KNowLns,

, a citizen of the United States, and resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Antismutting Devices for Traveling Sheets, of which the following is a specification.

The object of my invention is to provide a novel means for preventing'the smutting of traveling sheets, and it is particularly intended for use in preventing the smutting of sheets as they are passed first in one direction and then in another direction through the folding mechanism of a folding machine, which means is arranged to present a rolling support for a sheet traveling first in one direction and next in another direction at an angle thereto.

My invention more particularly consists in a device comprising a rotary wheel hav-' lng an annular series of rotary disks, the axes of which disks are at right angles to the axis of the rotary wheel, so that when the device is engaged with a sheet traveling in one direction, the wheel will rotate and when the sheet is traveling in another direction at right angles toits first direction, the particular disk or disks which engage the sheet will rotate, while the wheel may remain stationary.

A practical embodiment of my invention is illustrated in the accompanying drawings in which the embodiment is shown as applied to a folding machine of well known construction.

Figure 1 is a detail vertical section taken from front to rear through so much of a sheet folding machine as will illustrate the application of my invention.

Fig. 2 is a detail horizontal section taken in the plane of the line AA of Fig. 1.

Fig. 3 is a detail transverse section taken in the plane of the line BB of Fig. 1.

Fig. 4; is a plan view of one of my antismutting devices.

Fig. 5 is a side view of the same, and

' Fig. 6 is a section taken in the plane of the line C-C of Fig. 5.

In the folding machine in connection with which I have chosen to illustrate my invention, the sheets are fed longitudinally on to the folding table 1, into engagement with the front stop 2, by the usual upper and lower marginal endless tape carriers 3 and 41, into position over the folding slot 5 in the table, between the longitudinally arranged stationary folding blades 6 and the reciproeating foldinggrippers 7, which grippers are. operated any well known or approved means. These folding grippers 7 coact with the stationary folding blades 6,

through the slot 5,.in the tablel, to first crease the sheets longitudinally of their travel over the edge of the folding blade along the intended line of fold, and to afterward complete the folding of the so creased sheet by drawing itfrom the folding blade through said slot in the table and to thereafter deliver the so folded sheet to any desired point.

As the freshly printed sheet is moved longitudinally along the table intoengagement with the front stop, and then laterally by the folding of the sheet through the table, the printed matter on the under side of the sheet is liable to come into contact with the table and become smutted. I have provided a rolling support for the sheet, both as it IS moved longitudinally into its folding position and also when it is moved laterally during its folding operation, which support I will now describe in connection with thefolding machine herein illustrated and described.

A bracket 8 is provided with a stud axle 9, on which axle is mounted the hub 10 of a rotary wheel 11. This rotary wheel 11.

may be held in position on the stud 9, by a washer 12 and screw 13. This wheel is provided with an annular series of radial slots 14 opening through its periphery and the periphery of the wheel is provided with a shallow groove 15 in which is seated a split ring 16. This split ring may be fixed against 'rotative movement on the wheel 11, as for instance, by providing the wheel with a stud or pin 17 interposed between the ends of the split ring 16. This ring 16 is preferably made of spring material so as to snugly seat in the peripheral groove 15 of the wheel.

An annular series of radial disks 18 are rotatively mounted on the split ring 16, which disks are preferably toothed so as to present a very small engaging surface to the sheet traveling over the same. The inner portions of these disks are located within the radial slots 14 of the wheel, the outer portions of these disks project beyond the split peripheral ring 1670f the wheel.

the folding blade and'its cooperating grippers, the parts being so arranged thatthe disks 18 on the wheel 11 project above the surface of the table into position toengage the under side of the sheet-as ittravels into its folding position on the table. It will .be

' understood that any numberoffthese devices may be employed andtha't-theymay be -located in any desired positionon'thetable. It will be seen that. these antismutting 7 devices not only'cserve toprevent the smutting of the under sideof the sheet by contact with the table, but also serve as an antifriction support for the sheet it is'tr'aveling in both of its directions on the said table. '7

What Iclaim is:

1. An antismutting device for traveling printed sheets including a rotary wheel having a peripheral split ring, a plurality of radial disks rotatably mounted on said ring and means for maintaining the split ring in position on the.wheel.;-;

' 2. An antismutting" device for traveling printed sheets including agrotary Wheel hav-.

ing a peripheral, split ring a plurality of radial disks rotatably mounted on said ring,

and apin; or stud on said wheel interposed between the ends of the split ring for main: tamingthe ring in position on the wheel.

In testimony, that I claim the foregoing as my invention, have signed my name, this. 5th day of November, 1915.-- i BERNARD D. KNQWLE S,
